Direzione di ricerca

The panic comes from the loadDecl switch in cl/preload.go, which has no case for Cursor_ConversionFunction, though the class-local newClassCtx path already handles it; compare the two to see how that cursor kind is treated. Reproduce by generating bindings for the Async++ headers with llcppg as described in the issue, or start from explicit operator bool() in ref_count.h:146. Done when that header no longer panics with kind 26 and the conversion operator is handled consistently with the existing path.

Descrizione

bug

Observed failure

The recursive installed-header generation for Async++ reaches explicit operator bool() const in async++/ref_count.h:146 and panics in loadDecl with cursor kind 26.

panic: .../include/async++/ref_count.h:146:2: loadDecl: unknown kind - 26
github.com/goplus/llcppg/cl.loadDecl
    cl/preload.go:152

Confirmed Linux arm64 CI job. Formula testing and both compiler/tool builds succeeded; Test llcppg generation is the failing step. Other matrix jobs were still pending when this report was prepared, so this is not a claim that every platform has reproduced the failure.

Versions and reproduction input

  • llcppg: 8fc0f987e41ffe4b4f608e9541422b460ea89fea.
  • LLGo: afe9a5407260348b18c7104e98d76cb5cdf48b29; LLVM 21, Linux arm64.
  • Actual installed source: Amanieu/asyncplusplus v1.2, commit 4159da79e20ad6d0eb1f13baa0f10e989edd9fba, ref_count.h.
  • Failed configuration is from index PR #7, head 49abce7:
{
  "Name": "async",
  "Language": "c++",
  "Dir": "./include/...",
  "LLGoPackage": "link: $(pkg-config --libs async++)",
  "NSPrefix": ["async::"]
}

Stage the installed headers under source/include, initialize the source Go module as in the linked workflow, and run llcppg -v ./generated ./source. There is no Files allowlist or ignored API in this configuration.

Expected behavior and source evidence

A valid conversion operator should not fall into an unknown-cursor panic. The current-main loadDecl switch handles CXX methods, constructors, and destructors, but not Cursor_ConversionFunction. The same file's class-local newClassCtx path does handle Cursor_ConversionFunction, so the existing handling does not cover the path reached by this input.

Latest main (aab6dbf0baedc47b42f9576a65dd79ce6715e31a) was inspected only, not executed. The job also logs missing-package warnings for some GCC 14 C++ headers; their causal relationship to this panic has not been established and is not asserted here.
